“…The total annual potato production is approximately 400 million tons worldwide, and the major producing countries are China, India, Russia, the United States, and Ukraine (Celik et al, 2019). In 2020, China's annual potato production accounted for approximately a quarter of the world's total production, ranking first in the world (Tiwari et al, 2021). However, potatoes are severely damaged during the mechanized production steps, such as harvesting, transportation, grading, and storage (Li et al, 2018), where 70% of the damage occurs during the harvest (Peters, 1996; Wei et al, 2018).…”

The economic losses caused by collision damages during mechanical potato harvesting are significant. In this study, the simulation analysis method was used to investigate the factors affecting these mechanical damages. Taking the typical early maturing potato variety Zaodabai as an example, our test results indicated that its elastic modulus is 3.148 MPa, Poisson's ratio is 0.45, and biological yield stress is 1.183 MPa. An accurate three-dimensional potato model was created using reverse engineering technology. On this basis, the effects of drop height, collision mode, and collision material on the mechanical potato damage were investigated using finite element analysis. The results indicated that the potato damage characteristics become more evident as the drop height increased.Analyzing the collision mode of mechanized potato harvesting revealed that the potato damage degree is the lowest in the double-rod long axis collision mode. The collision damage degree between a potato and four common collision materials was determined from highest to lowest as follows: 65 Mn rod, 65 Mn rubber-coated rod, potato, and soil. This research provides a data basis and reference for the design and development of potato harvester equipment, particularly for low-damage potato harvesters. Practical applicationsAs the fourth largest food crop in the world, potatoes have high economic value and are of great importance for food security. Collision damage in mechanized harvesting seriously reduces the quality and value of potatoes and causes large economic losses.Therefore, we aim to clarify the key factors affecting collision damage in mechanized harvesting. The influence of motion mode, collision height, collision method, and collision material on potato damage characteristics was investigated through simulation experiments. This study provides a data basis and reference methods for developing key components of high-performance and low-damage potato harvesters and serves as a reference for researching damage characteristics of other tuber, root, and bulb crops.

“…Central Java Province is the second largest potato producer in Indonesia, with production reaching 307.6 tons in 2020 [2]. In current cultivation, potato is planted in the highlands, above 1,000 m.a.s.l, which humid condition also triggers the emergence of wilt disease caused by Ralstonia solanacearum infection [3,4] or Fusarium sp [5,6] and late blight caused by Phytophthora infestans (Mönt.) de Bary [7].…”

Potato cultivation in the middle land is an alternative solution to avoid pathogens. Although it reduces potato quantity and requires more chemical fertilizers to increase production that potentially damages the environment. Therefore, this study aims to characterize contaminations and indigenous microbes from semi-organic potato cultivation centers in Central Java. Soil samples from the semi-organic potato cultivation center of Kledung, Central, were analyzed for metal contamination using the atomic absorption spectrophotometry method and metagenomic soil bacterial diversity profiles. Specifically targeted genes of distinct regions 16SV3-V5. OTUs were identified using Uparse v7.0.1001, while Beta diversity analysis used UniFrac. All these indices in our samples were calculated with QIIME (Version 1.7.0) and displayed with R software (Version 2.15.3). The results showed that semi-organic cultivations had been polluted with Pb > Cd > Cr > As, and carbamate residue was detected in the rhizosphere and surface soil. Manure and compost application alongside NPK fertilizer increases N input, decreasing surface soil bacteria. The surface soil (with a depth of ≤ 5 cm) has a lower index of species richness, diversity, and relative abundance than the rhizosphere layer (depth > 5 cm). Firmicutes, Proteobacteria, and Actinobacterium dominate soil-level bacteria. In comparison, the rhizosphere soil has a higher bacteria diversity dominated by N-tethering rhizobia from the phylum Proteobacteria. The potato root attracts rhizobacteria consortium that support plant growth. A further study should be conducted to describe how the bacterial consortium formed, rhizobia migration from surface to rhizosphere soil, and its interaction with the potato plants. HIGHLIGHTS Semi-organic potato cultivation in Kledung, Temanggung, Indonesia, is contaminated with heavy metals, especially Pb, which is the highest pollutant, and the carbamate residue Excessive nitrogen (N) input from organic and chemical fertilizers reduces the diversity of soil surface bacteria Then manure application as organic fertilizer introduces pathogenic bacteria such as Eschericia-Shigella, Faecalibaculum, Fusobacteria, Bacilli, and Enterococcus The rhizosphere soil is dominated by N-fixating rhizobia from Proteobacteria, including Pseudoxanthomonas Mexicana, Lysobacteria , Devosia riboflavina, Aminobacter sp., Bosea sp., Allorhizobium, Neorhizobium, Pararhizobium, and Rhizobium GRAPHICAL ABSTRACT

“…Potato ( Solanum tuberosum L.) ranks as the fourth largest food crop in the world after wheat, rice, and corn ( Iqbal et al, 2019 ; Reyniers et al, 2020 ). Its world production stands at 376.8 MT per year produced from 19.2 Mha ( Tiwari R. K. et al, 2021 ), with reported pathogens yield losses of up to 17.2% ( Savary et al, 2019 ). If yield losses by pathogens are reduced, potato has the potential to meaningfully assist in achieving the first United Nations Organization’s ( Quiroz et al, 2018 ) development goal of eliminating poverty and malnutrition in the world ( Chávez-Dulanto et al, 2021 ).…”

Potato (Solanum tuberosum L.) is one of the most important crops in maintaining global food security. Plant stand and yield are affected by production technology, climate, soil type, and biotic factors such as insects and diseases. Numerous fungal diseases including Neocosmospora rubicola, causing stem rot, are known to have negative effects on potato growth and yield quality. The pathogen is known to stunt growth and cause leaf yellowing with grayish-black stems. The infectivity of N. rubicola across a number of crops indicates the need to search for appropriate management approaches. Synthetic pesticides application is a major method to mitigate almost all potato diseases at this time. However, these pesticides significantly contribute to environmental damage and continuous use leads to pesticide resistance by pathogens. Consumers interest in organic products have influenced agronomists to shift toward the use of biologicals in controlling most pathogens, including N. rubicola. This review is an initial effort to carefully examine current and alternative approaches to control N. rubicola that are both environmentally safe and ecologically sound. Therefore, this review aims to draw attention to the N. rubicola distribution and symptomatology, and sustainable management strategies for potato stem rot disease. Applications of plant growth promoting bacteria (PGPB) as bioformulations with synthetic fertilizers have the potential to increase the tuber yield in both healthy and N. rubicola infested soils. Phosphorus and nitrogen applications along with the PGPB can improve plants uptake efficiency and reduce infestation of pathogen leading to increased yield. Therefore, to control N. rubicola infestation, with maximum tuber yield benefits, a pre-application of the biofertilizer is shown as a better option, based on the most recent studies. With the current limited information on the disease, precise screening of the available resistant potato cultivars, developing molecular markers for resistance genes against N. rubicola will assist to reduce spread and virulence of the pathogen.
